Table 3.
Fitness tradeoffs across environment for lifetime fecundity of all plants. Plants that failed to set fruit were assigned fitness = 0 and then family means (LSMEANS) were calculated in SAS. Raw fitness data were used in the analysis of the Montana 2008 cohort, but fitness required log transformation for the 2009 cohort and both cohorts combined.
